Watch Barrie McKay score one of the greatest ever Old Firm goals

When a match has a huge build-up, it can often end up disappointing.

But that was far from the case when Rangers and Celtic met in the semi-finals of the Scottish Cup. Rangers won a thrilling penalty shoot-out 5-4 after an entertaining 2-2 draw, with Celtic's Patrick Roberts missing an open goal in normal time. The highlight for many, though, was Barrie McKay's extra-time thunderbolt. https://twitter.com/timeaddedon91/status/721685035414384640 Twenty-one-year-old McKay has been with Rangers since he was a teenager, making the strike even sweeter. And it's safe to say Gers fans were impressed. https://twitter.com/JohnnyUtah100/status/721694814157283328 https://twitter.com/euangtaylor/status/721695670625767424 https://twitter.com/sunshinekid10/status/721695300256145408 https://twitter.com/Ryanblyth03/status/721695629626499072
